Description

Technical Field

[0001] The present invention relates to the technical field of gellan gum, in particular to continuous production equipment for gellan gum. Background Art

[0002] Gellan gum, also known as kelp gum or gellan gum, is a microbial polysaccharide produced by Pseudomonas elodea. Its main components are glucose, glucuronic acid, and rhamnose in a 2:1:1 ratio. It is a linear polysaccharide composed of four repeating monosaccharides. Gellan gum is produced by pure culture and fermentation of carbohydrates (such as glucose and sucrose) by microorganisms such as Pseudomonas elodea or Sphingomonas paucimobilis. It is refined through fermentation, pH adjustment, clarification, precipitation, pressing, drying, and grinding.

[0003] A Chinese invention patent, publication number CN212820166U, discloses a gellan gum production pulverizer that facilitates feeding and has a drying function. The pulverizer comprises a pulverizing chamber and an inclined plate. The outer wall of the pulverizing chamber is surrounded by an insulation layer, the outer wall of the insulation layer is surrounded by an outer wall of the pulverizer, the inner middle end of the insulation layer is connected to a heating pipe, and the upper end of the insulation layer is connected to an inclined plate. The lower end of the outer wall of the pulverizer is connected to a non-slip base. The lower middle end of the outer wall of the pulverizer is provided with a discharge port. The inner bottom end of the outer wall of the pulverizer is connected to an air chamber, and one side of the upper end of the air chamber is connected to an air jet. The gellan gum production pulverizer that facilitates feeding and has a drying function is provided with an insulation layer. The insulation layer between the pulverizing chamber and the outer wall of the pulverizer can fully insulate the raw materials inside the entire device, keeping the interior of the device dry. A heating pipe is also installed inside the insulation layer, and the raw materials can be dried through the internal heating pipe.

[0004] In addition, because existing fermentation tanks are stirred by anchor agitators, the viscosity of the fermentation liquid increases with the formation and accumulation of gellan gum, and a dead zone is prone to occur. In other words, only the fermentation liquid around the blades rotates with the blades. The farther away from the stirring blades, the lower the kinetic energy, velocity, and gas content of the fermentation liquid. The fermentation liquid at the tank wall is almost static, which can inhibit cellular metabolism, divert sugar metabolic pathways, and sharply reduce the gum production rate and sugar conversion rate. In addition, during the filter press process, uneven feed rate, inconsistent filter cake thickness, or poor filter plate sealing can all lead to fluctuations in filtration pressure. The filter cake itself has a certain degree of viscosity and easily sticks to the inside of the filter press, making it difficult for the operator to remove it and affecting production efficiency. Therefore, the grinder for gellan gum production disclosed in Chinese invention patent CN212820166U, which is easy to feed and has a drying function, cannot fully stir the gellan gum and cannot ensure the stability of the pressure of the filter press.

[0048] It should be noted that: the ball rods 3059 are symmetrically arranged at the upper and lower ends of the arc - shaped sliding groove 3055, so that the arc - shaped sliding groove 3055 drives the second contact rod 3071 and the first pressure - filtration plate 3072 to approach and separate during rotation.

[0050] The working process and principle of the above embodiment are as follows:

[0051] Initial state: The elastic telescopic rod 2066 is in an unextended state. The ball rod 3059 fixedly connected to the outer wall of the connecting plate two 3058 is at the top of the arc-shaped chute 3055 close to the fixing plate three 3056. The ball rod 3059 fixedly connected to the outer wall of the connecting plate one 3057 is at the top of the arc-shaped chute 3055 away from the fixing plate three 3056.

[0052] The working steps are as follows:

[0053] First, the operator connects the feeding device to the feeding port 2041, so that the material to be fermented falls into the inside of the fermentation cylinder 202 through the feeding port 2041. Subsequently, the feeding port 2041 controls the rotation of the rotating block 2048, so that the rotating block 2048 drives the threaded rod 2047 to rotate on the inner wall of the baffle one 2044, so that the threaded rod 2047 drives the stirring tank plate 2061 to move away from the diversion tank plate 2063, so that the stirring tank plate 2061 drives the diversion tank plate 2063 to move synchronously.

[0054] During the rotation of the rotating block 2048, the rotating block 2048 drives the groove 1 2049 and the contact rod 1 20410 to rotate synchronously, so that the contact rod 1 20410 rotates to the inside of the groove 2 20414, and the fixed plate 1 20413 moves to the inside of the groove 1 2049, thereby causing the contact rod 1 20410 to contact the inner wall of the groove 2 20414, so that the groove 20414 drives the fixed plate 1 20413 and the fixed rod 1 20411 to rotate synchronously. The first step intermittently rotates on the outer wall of the baffle 2044, so that the fixed rod 20411 drives the gear 20412 to rotate synchronously, so that the gear 20412 drives the annular gear plate 2046 engaged therewith to rotate synchronously, so that the annular gear plate 2046 drives the rotating plate 2045 to rotate at the connection between the connecting rod 102 and the fermentation cylinder 202, and the sealing strip provided on the rotating plate 2045 seals the fermentation cylinder 202, and then the rotating plate 2045 drives the scraper 2069 The scraper 2069 rotates synchronously inside the fermentation cylinder 202, so that the scraper 2069 scrapes the liquid attached to the inner wall of the fermentation cylinder 202, so that the scraper 2069 drives the guide groove plate 2063 to start rotating on the threaded rod 2047, so that the guide groove plate 2063 drives the stirring frame 2062 to rotate synchronously. At the same time, under the drive of the stirring groove plate 2061, when the guide groove plate 2063 moves to the side away from the rotating plate 2045, the stirring groove plate 2061 drives the elastic telescopic rod 2062 to rotate synchronously. 066 and baffle 2067 move synchronously, so that baffle 2067 is always in contact with the stirring trough plate 2061 under the resistance of the liquid, and the stirring trough plate 2061 pushes the liquid in the middle of the fermentation cylinder 202, and the liquid intermittently flows between the stirring trough plate 2061 and the fermentation cylinder 202 to the side of the stirring trough plate 2061 close to the slot 2064, thereby increasing the contact frequency between the middle of the fermentation cylinder 202 and the liquid at both ends, and improving the fluidity of the liquid inside the fermentation cylinder 202.

[0055] Subsequently, the controller 2042 controls the rotating block 2048 to start rotating in the reverse direction, so that the rotating block 2048 drives the first fixing plate 20413 to rotate synchronously and intermittently in the reverse direction, so that the first fixing plate 20413 drives the rotating plate 2045 and the annular toothed plate 2046 to rotate synchronously in the reverse direction through the gear 20412, so that the rotating plate 2045 drives the scraper 2069 to move synchronously, so that the rotating block 2048 drives the stirring tank plate 2061 to move towards the side close to the annular toothed plate 2046 through the threaded rod 2047, so that the stirring tank plate 2061 drives the diversion tank plate 2063 to move synchronously, so that the diversion tank plate 2063 drives the scraper 2069 to drive the diversion tank plate 2063 to rotate synchronously in the reverse direction, and drives it to move towards the side close to the rotating plate 2045 under the abutting action of the stirring tank plate 2061. During the reverse rotation of the diversion tank plate 2063, the diversion tank plate 2063 drives the stirring paddle 2065 to rotate synchronously in the reverse direction, so that the stirring paddle 2065 abuts against the liquid in a bevel-cut manner and guides it to flow into the interior of the diversion tank plate 2063 and the stirring tank plate 2061, and makes the liquid entering the diversion tank plate 2063 and the stirring tank plate 2061 start to rotate. Furthermore, during the rotation of the liquid in the stirring tank plate 2061, it frequently collides with the stirring frame 2062. Subsequently, the rotating liquid abuts against the blocking rod 2068 and drives the second baffle 2067 to move towards the side away from the stirring tank plate 2061, so that the second baffle 2067 drives the elastic telescopic rod 2066 to extend towards the side away from the stirring tank plate 2061. Finally, the stirred liquid enters the middle of the fermentation cylinder 202 through the filter holes opened on the stirring tank plate 2061 and continues the next stirring. By the stirring paddle 2065 pushing the liquid into the interior of the stirring tank plate 2061, the volume of the liquid inside the stirring tank plate 2061 is reduced, and thus the movement range between the liquid solutes can be reduced. By the stirring frame 2062 stirring the liquid inside the stirring tank plate 2061, the collision frequency between the liquid solutes inside the stirring tank plate 2061 and the stirring frame 2062 is increased, preventing the phenomenon of liquid solutes aggregating, improving the contact frequency between different liquid solutes, and thus improving the mixing uniformity of the fermentation broth.

[0056] When the liquid fermentation is completed, the controller 2042 controls the second fixed plate 3054 to rotate on the second fixed rod 3053, so that the second fixed plate 3054 can move back and forth in the horizontal direction through the arc chute 3055 against the ball rod 3059, thereby causing the arc chute 3055 to contact the ball rod 3059 and drive the second connecting plate 3058 to move away from the second fixed plate 3054, so that the arc chute 3055 can contact the ball rod 3059 and drive the first connecting plate 3057 to move toward the side close to the second fixed plate 3054, thereby causing the filter press plate 3051 to move back and forth in the horizontal direction. 72 drives the second contact rod 3071 to squeeze each other closer. When the pressure plate 3075 enters the interior of the loading tank 3073 and blocks the loading tank 3073, the controller 2042 controls the extraction port 3051 to extract the liquid inside the fermentation cylinder 202, so that the liquid enters the interior of the filter plate 1 3072 through the guide hose 3052 and fills the loading tank 3073 with the liquid. Then the pressure plate 3075 continues to move toward the interior of the loading tank 3073 and squeezes and dehydrates the liquid inside the loading tank 3073. After the filtration is completed, the controller 2042 controls the second fixed plate 3054 to drive the second connecting plate 3058 and the first connecting plate 3057 to move away from the second fixed plate 3054 through the ball rod 3059, so that the first connecting plate 3057 drives the second filter press plate 3074 to separate from the first filter press plate 3072 driven by the second connecting plate 3058, and then moves the second contact rod 3071 to the inside of the loading tank 3073, and makes the second contact rod 3071 contact the loading tank 3073 to remove the filter cake left after the filtration is completed, so that the filter cake is moved to the loading tank 3074. 73 moves externally, causing the filter cake to fall onto the top of the filter plate 303, and enter the interior of the loading tank 3073 through the pressing plate 3075 to filter the condensed liquid, thereby ensuring the consistency of the filter cake size after filtration. The filter cake is automatically separated by the resistance rod 2 3071, avoiding the problem of the filter cake being too sticky and difficult to take. The arc-shaped slide groove 3055 drives the filter press plate 2 3074 and the filter press plate 1 3072 to be repeatedly squeezed and separated, thereby increasing the continuity of the filter cake separation and filtration process, and improving the filtration efficiency of preparing the filter cake.
